Thanks for the bug report. Next time the slowdown happens, or even
before it does, please run this command:
ps -eo pid,rss,cmd --sort -rss > toprss.txt
and attach the resulting text file here. It will tell us which processes
are using the most memory.

Title:
GNOME Wayland session slows down, mouse skips until the desktop
freezes
Status in Ubuntu:
Incomplete
Bug description:
I am observing multiple issues with external monitor in a hybrid
system (laptop) with Intel GPU and NVIDIA GPU in a Gnome session:
- I typically use Firefox with several tabs opened and Visual Studio
Code. Some times at least once a day I notice a severe performance
degradation. The desktop becomes unresponsive. The mouse cursor skips.
GNOME popups up dialogs proposing to close my applications. If I
manage to reboot it is all fixed. Sometimes the system locks up
completely. This seems like a severe memory leak.
I have not noticed it on previous versions. I use the latest updates
and drivers of 22.04 LTS.
I am not sure how to auto-report this with ubuntu-bug. The system is
similar to this report:
